Connecting rods are made in two pieces — a cap and beam section, held together with nuts and bolts. Cast semi-steel connecting rods are making a return in production engines thanks to their comparatively low cost and ease of manufacture. Their main drawback is their weight, typically some 100 grams heavier than their forged counterparts.sp.info CONNECTING ROD INSPECTION - MOTORrod bore has been pulled out-of-round. If out-of-round by .002 in. or less, the rod big-end may be honed .002 in. to correct, and then fitted with +.002-in. O.D. rod bear-ings. If an OE powdered-metal connecting rod is more than .002 in. out-of-round, replace it. Photos: Jim Gibsonsp.info Connecting Rod Honing Basics | Goodson Tools & SuppliesRod Honing.

As we’ve talked about in previous articles, all connecting rods have a parting edge. Most are flat surfaces machined into the cap and rod sections. These surfaces must be straight and perpendicular to the rod sides. If they aren’t, cap misalignment can reduce clearance between the rod and the crankshaft journal.See all results for this questionsp.info Amazon.com: 4 inch buffing padsuxcell 4 Inch 10000 Grit Diamond Wet Polishing Pad Set, for Stone Concrete Marble Grinder or Polisher, with M14 Hook and Loop Backing Holder Pad Connecting Rod $13.99 $ 13 . …sp.info Assembly Instructions TVR1A53064 2 Pin, Crosshead - Connecting Rod 53070 1 Base, Machined 53071 1 Cylinder Mount 53073 4 Column, 2 1/8” long 530742 Bellcrank 53075 2 Eccentric Strap 530762 Eccentric 53083 4 Bearing, 3/16” ID 53084 2 Slide, T-Slot, Male 53086 1 Bar, Valve Detent 53087 2 Link, Offset 53088 2 Link, 2 hole 53089 2 Fork, Rod End, 0-80 Internal Threadsp.info TECH INFORMATION FROM CLEVITE ENGINE PARTSConnecting rods are subjected to high inertia loads at the top of the exhaust stroke when the weight of the piston, rings, wrist pin and top end of the rod are all pulling on the rod cap.
